To all whom it may concern:

Be it known that I, ELBERT B. BAILEY, a citizen of the United States, residinv at Mart, in the county of McLennan and'S tate of Texas, have invented certain new and useful Improvements in 'Powder-Dusting Attachmentsyof which the-following is. a specification, v

invention relates toa-device' preferably embodied in an attachment, to heapplied' to or'u'sed' inconnec'tion with a cultivator, or like wheeled agricultural impleinent, forapplyinganinsecticide, prefer ably in'a powdered form, to plants, such as the cotton plant," for-destroying boll .An; important object of the invention' is to provide attachment of the above mentioned character; which 'nray be applied to 'the ordinary cultivator, without materlally altering the construction thereof;

' "further object of the invention is to -.disk-val;ve, w-Figure'? is alperspecti-ve view. of the -presprovide a device of the "above mentioned character,- which is adapted to properly spray a pluralitjr' of rows f la t at file same ti'me; H I l v A further object of the" invention is to a provide means" for properly agitating the powdered insecticide, while in-the hopper,

" 1 ing frame", including. outer longitudinalbars 22,. extending longitudinally of the machine and feeding the sanie in proper amounts, into thepressure chamber or casing.

@thei objects and advantages of the invention will be apparent during the course of the following i description."

The numeral 41 designates a rotatable disk-valve, operating between the bottom 30 and false bottom 39, and having preferably curved'slots 42-formed therein, providin spaced fingers 43, preferably connecteil by a rim 44. The disk-valve has an upwardly offset hub 45, receiving a boss 46 formed upon the bottom 80.

The disk-valve is rotated by a vertical shaft 47, extending'through an opening in the boss 46 and an opening in the hub 45. The shaft carries a transverse pin 48, fitting within openings or recesses 49 in the hub 45, whereby the disk-valve rotates with the vertical shaft. The upper end of the shaft 47 is screw-threaded, at 50, for engagement with a coupling 51, rigidly secured to an agitator hub 52, carrying radially extend ing arms 53, having downwardly bent ends 54. 1

The means to drive the shaft 47 includes a bevel gear 54, suitably connected with its lower end, and engaging a bevel gear 55, rigidly secured to a transverse driving shaft 56. This shaft is journaled in bearings 57, integral with the angle irons 27. One end of the shaft 56 is journaled in a bearing 58, carried by a diagonal brace 59, which may be clamped to the vertical portion of the axle. A clutch element 60 is rigidly secured to one end of the shaft 56, and has ratchet teeth to engage with ratchet teeth formed upon a coact ing clutch element 61, rotatable upon the shaft 56, and moved inwardly by the spring 62. A sprocket wheel 63 is formed integral with the clutch element 61 and engages a sprocket chain'64 extending forwardly to engage a sprocket wheel 65, connected with one wheel 13, for rotation therewith. The function of the clutch elements is to provide means whereby the disk-valve and agitator will be driven when the cultivator is traveling forwardly, but will not be operated when the machine is being turned around or moved rearwardly.

The numeral 66 designates a rotary blower, embodying a casing arranged upon and supported by a transverse bar 67, bolted to the bars 15. This blower casing is arranged in advance of the hopper 29, and

p the fan element of the blower is driven by a transverse shaft 68, having one end journaled in the blower casing, and the other end in a bearing 69, carried by the bar 15. A sprocketwheel 70 is rigidly secured to the outer end of the shaft.68, and engages a sprocket chain 71 extending rearwardly to engage a sprocket wheel 72, rigidly secured to the shaft 56. The blower casing has its outlet end connected with a pipe or hose 73, see Figure 4, connected with a casing 74, having an opening 75 to receive the lower end of the pipe 37. The casing 74 is adapted to telescope within a pressure casing or chamber 75, and may be clamped therein by a. set screw 76 or the like. A plurality of corqalings 77 are secured to the forward end lows: The cultivator is drawn forwardly over the rows of plants, and the disk-valve 41 is rotated, with the agitator. The powdered material within the hopper 29, is stirred by the agitator, and falls into each slot 42 as it is brought in registration with the opening 38, the extent of this opening being regulated by slide valve 38'. The powdered material is carried around and dropped into and through the opening 36, and passes through pipe 37 into casing 74, and is blown'by the compressed air from the blower through casing 75, and hose 78 to or upon the plants. By swinging the extensions 24 outwardly to assume a horizontal position, Figs. 1 and 9, the hose '7 8 may have their outer ends suitably supported, and this will increase the transverserange of the machine. I

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same, and that various changes in the shape, size, and arrangement of parts may be resorted to without departing from the spirit of my invention, or the scope of the subjoined claims.

Having thus described my invention, I claim::- I.

1. In an attachment for a cultivator or the The operation of the machine is as follike including an arched axle, an'inner longitudinally extending attaching frame disposed above and contacting with the arched portion of the axle, a blower arranged upon the forward side of the arched axle and connected with the attaching frame to" be supported thereby, a'hopper arranged upon the rear side of the arched axle and connected with the attaching frame to be supported thereby, a pressure chamber for receiving material from the hopper and connected with the blower to receive air under pressure therefrom, means to drive the blower, an outer supporting frame extending longitudinally beneath the arched portion of the axle and suspended therefrom, means con necting the forward end of the attaching frame with the forward end of the outer and connected with the blower,

supporting frame, a transverse supporting bar connected with the rear end of the outer supporting frame, and a plurality-of conduits connected with the pressure receptacle and adapted to be supported by the supporting bar.

2. In an attachment for a cultivator or'the i like including an arched axle, an inner longitudinally extendlng attaching frame arran ed above and resting upon the arched portion of the axle, a transverse bar 0011- upon the rear side of said arched portion and supported within the attaching frame, a pressure chamber connected with the hopper feeding means to discharge material from the hopper into the pressure receptacle, means to drive the blower and feeding means, and a plurality of conduits connected with the pressure receptacle and extending rearwardly to be arranged upon the rear end of the outer supporting frame.

3. In an attachment for a cultivator or the like, a longitudinally extending frame secured thereto, a transverse bar connected with the rear end of the supporting frame, a pair of extension bars pivotally connected with the ends of the transverse bar to swing longitudinally of the transverse. bar and transversely of the supporting frame, U-.

shaped stops carried by the extension bars and adapted to engage over the transverse bar, a plurality of conduits adapted to have their free ends supported by the transverse bar and bar extensions, and meansto blow finely divided material through the conduits, v In testimony whereof I aflix my signature.
